$xml = simplexml_load_file('Request.xml');
$xml->registerXPathNamespace("ess", "localhost/ESS");
$partnums = array();

$xp = "descendant::ess:ProPartList/ess:ProPart/ess:SelectedPart";
$selected = $xml->xpath($xp);        
$x = 0;
foreach($selected as $part) {
    $partnuminfo = $part->xpath("//ess:PartNumInfo");
    foreach($partnuminfo as $p) {
        echo $p->asXML();
        $_Type = (string)$part->children("ess",true)->PartNumType;
        $partnums[$x] = array($_Type => (string)$part->children("ess",true)->PartNum);
        $x++;
    }
}
print_r($partnums);

使用上面的代码,我似乎无法理解如何解析下面的XML:

<ess:ProInfo>
    <ess:ProPartList>
        <ess:ProPart>
            <ess:SelectedPart>
                <ess:PartNumInfo>
                    <ess:PartNumType>OE</ess:PartNumType>
                    <ess:PartNum>04715SNAA90ZZ</ess:PartNum>
                </ess:PartNumInfo>
                <ess:PartNumInfo>
                    <ess:PartNumType>IC</ess:PartNumType>
                    <ess:PartNum>536-01037</ess:PartNum>
                </ess:PartNumInfo>
                <ess:PartNumInfo>
                    <ess:PartNumType>PType</ess:PartNumType>
                    <ess:PartNum>536</ess:PartNum>
                </ess:PartNumInfo>
            </ess:SelectedPart>
        </ess:ProPart>
        <ess:ProPart>
            <ess:SelectedPart>
                <ess:PartNumInfo>
                    <ess:PartNumType>OE</ess:PartNumType>
                    <ess:PartNum>71570SNAA00</ess:PartNum>
                </ess:PartNumInfo>
                <ess:PartNumInfo>
                    <ess:PartNumType>IC</ess:PartNumType>
                    <ess:PartNum>536-01036</ess:PartNum>
                </ess:PartNumInfo>
            </ess:SelectedPart>
        </ess:ProPart>
        <ess:ProPart>
            <ess:SelectedPart>
                <ess:PartNumInfo>
                    <ess:PartNumType>OE</ess:PartNumType>
                    <ess:PartNum>66100SNEA00ZZ</ess:PartNum>
                </ess:PartNumInfo>
                <ess:PartNumInfo>
                    <ess:PartNumType>IC</ess:PartNumType>
                    <ess:PartNum>117-50338</ess:PartNum>
                </ess:PartNumInfo>                                
            </ess:SelectedPart>
        </ess:ProPart>
        <ess:ProPart>
            <ess:SelectedPart>
                <ess:PartNumInfo>
                    <ess:PartNumType>OE</ess:PartNumType>
                    <ess:PartNum>04655SNE305ZZ</ess:PartNum>
                </ess:PartNumInfo>
            </ess:SelectedPart>
        </ess:ProPart>
    </ess:ProPartList>
</ess:ProInfo>

创建这个数组()

array(
    0 => array("OE" => "04715SNAA90ZZ", "IC" => "536-01037", "PType" => "536"),
    1 => array("OE" => "71570SNAA00",   "IC" => "536-01036"),
    2 => array("OE" => "66100SNEA00ZZ", "IC" => "117-50338"),
    3 => array("OE" => "04655SNE305ZZ")
)

我认为主要的问题是 //ess:PartNumInfo 在第二个xpath表达式中,这也会导致找到其他元素(///表示任何元素)。如果你把它改成 descendant:: axis和第一个xpath表达式一样,它将只查找起点内的元素。

我已经更改了代码,以便在下一级对元素进行分组,所以…

$xp = "descendant::ess:ProPartList/ess:ProPart/ess:SelectedPart";
$selected = $xml->xpath($xp);
foreach($selected as $part) {
    $partnuminfo = $part->xpath("descendant::ess:PartNumInfo");
    $group = array();
    foreach($partnuminfo as $p) {
        $_Type = (string)$p->children("ess",true)->PartNumType;
        $group[$_Type] =(string)$p->children("ess",true)->PartNum;
    }
    $partnums[] = $group;
}
print_r($partnums);

给予。。。

Array
(
    [0] => Array
        (
            [OE] => 04715SNAA90ZZ
            [IC] => 536-01037
            [PType] => 536
        )

    [1] => Array
        (
            [OE] => 71570SNAA00
            [IC] => 536-01036
        )

    [2] => Array
        (
            [OE] => 66100SNEA00ZZ
            [IC] => 117-50338
        )

    [3] => Array
        (
            [OE] => 04655SNE305ZZ
        )

)
